I quit at 10 pm april 6......it has not been an easy few days LOL but...so worth it. Still have some shortness of breath. Today I have started coughing up some (well you all know gross stuff) but I feel good, I am coughing it up and out, not inhaling it in. I have copd and I have a nebulizer and emergency inhaler if breathing gets to be a problem. so far so good, I only used inhaler once.I will make it, we all will. Just have to believe in yourself and if you are a person of faith, believe and trust that He will help you thru the rough spots.
